Purpose

Creates a clockwise elliptical arc from Start to End point, with the ellipse specified by its bounding rectangle. 

Example

Description

In the diagram, the bounding box goes from Min = (X1,Y1) to Max = (X2,Y2) and the elliptical arc is clockwise with a start point (X4,Y4) and end point (X3,Y3). The start and end points do not need to be strictly on the ellipse - if not on it, then draw a radial line from the centre of the bounding box to the specified point, and where this intersects the ellipse will define the exact start or end point.

Fields

SecMin	The X, Y, Z co-ordinates of the min corner of the section which this machining step is inside.
SecMax	The X, Y, Z co-ordinates of the max corner of the section which this machining step is inside.
JoinMin	The X, Y, Z co-ordinates of the min corner of the section which this machining step is joined to.
JoinMax	The X, Y, Z co-ordinates of the max corner of the section which this machining step is joined to.
CutSize	X, Y, Z contain the values from this component dimcut1, dimcut2, dimcut3 respectively.
FinishedSize	X, Y, Z contain the values from this component dim1, dim2, dim3 respectively.
PartID	A name for this step, init as component name, not sent to DXF usually.
Layer	The layer name written to the DXF, init as steptype but you should set this to something more meaningful e.g. in EzyNest. In addition, this layer value can be prefixed by + - or ~. The prefix is not sent to the DXF, but is used to indicate notches, where two steps are combined. A + is for combining two steps by adding the paths together. This can extend the outer shape. A - is used for subtracting or creating a notch. And a ~ is for flap donor steps. (See Flaps In Remote Components)
Group	The group name written to the DXF. Default value is ungrouped. Different groups will be nested separately, so for example a DXF with some ungrouped machine steps and some steps in group 10 and others in group 20 will nest as three separate parts.
ColorIndex	The color used in the DXF (usually unused by Machining but very helpful for viewing). Colors are defined by Voloview DXF viewer. (See also DXF Layer Colours): 0 - Black 1 - Red 2 - Yellow 3 - Green 4 - Cyan 5 - Blue 6 - Magenta 7 - Black(Again) 8 - Grey 9 - Brown 10 - Khaki 11 - Dark Green 12 - Steel Blue 13 - Dark Blue 14 - Purple 15 - Dark Grey
Min	XY coordinates of lower left corner of a rectangle.
Max	XY coordinates of upper right corner of the rectangle.
Start	XYZ: location of start of the machining step.
End	XYZ: location of end of the machining step.
Depth	Depth of the of the cut/drill.
RepeatCount	X: Whole machine step is repeated this many times. Y: If this is >1, then do a rectangular array of repeats.
RepeatOffset	XY: Offset vector between copies (for linear repeats). For arrays of repeats, X is the X offset and Y is the Y offset. Here's a little example of a BorderDeco step repeated in a 3x2 array:
ProfileFolder	Folder for QPFs, default BitmapFolder, can be relative.
ProfileName	Name of the profile. The default extension is ".qpf". An array of names is allowed, if defining multiple profile edging.
ProfileEdging	Array of edge treatments. See Edge and Pocket Profile Tutorial : Defining a Profile
Pocket	Entry is a yes/no determining whether the area inside the machinestep is to be removed. Applies to contours (closed polylines only).   See Edge and Pocket Profile Tutorial : Pocket
